CEZ549
Cause:
This may occur if printed at low temperature or humidity.
Note:
• To adjust the following settings, pre-register the type of paper in use as a custom
paper. For details about registering custom papers, see "Registering a Custom
Paper", Paper Settings Reference.
• If you reduce the paper transfer current to eliminate white spots, copies may
become too faint.
Solution:
1.
Check both sides of the paper for the problem. If this problem appears only
on the side 2 of the paper, skip to Step 3.
2.
Adjust the setting for the side 1 of the paper. Configure the following settings
in [Advanced Settings] for the custom paper in use.
<Printing in black and white>
Decrease the absolute value of the negative current by 5% in [31: Paper
Transfer Current: B&W].
Example: If the present current is −40 μA, change it to −38 μA.
<Printing in full color>
Decrease the absolute value of the negative current by 5% in [32: Paper
Transfer Current: FC].
Example: If the present current is −70 μA, change it to −67 μA.
